Blow Molding and Reheat in Guelph, ON

Blow Molding and Reheat in Guelph, ON, is part of the two-stage process of making bottles from PET or other resins. During the first stage, injection machines produce vial or test-tube shaped ‘preforms.’ The necks of preforms are fully finished, but the diameter and length are much smaller than the bottle into which it will be transformed during the reheat stretch blow molding process. During this transformation, the material undergoes significant changes in molecular orientation, making PET bottles virtually unbreakable, lightweight, and enhancing various barrier properties while keeping the clarity that is also present in the preforms.

Making PET preforms and bottles has become a high-tech, extremely competitive business. The challenge for smaller companies is to compete with much larger corporations and carve out a niche for a profitable business. Large corporations have to stay ahead of the competition and spend their R & D Dollars wisely in blow molding package development. With the advent of increased barrier materials, hot-fill applications, coating technologies, etc. it has become more difficult to invest these Dollars in areas that make commercial sense. With our injection and molding experience in preform and bottle design and manufacturing technology, we can assist you in making the right decisions.
